Audio Research Reference 3 Seeking help

Dear Brothers,

I am Michael from Hong Kong. I bought my Audio Research Reference 3 Preamp from the previous authorized Hong Kong dealer in 2008. Now I intended to upgrade the said 4 pcs 0.0024 coupling caps inside the Ref3 but the present authorized Hong Kong dealer refused to help me to make such order.

Would you guys offer me assistance to that? Of course, I must pay you back the charges in advance, if any.

Thanks for your help.

Rgds,
Michael Cheung

ARC never used .0024mfd as a coupling cap. I do not know where you are getting your info from. That value is way too small for a coupling cap as well as for a bypass cap.

I would complain to ARC about this dealer, who would want to buy anything from such a person unwilling to help with a product he represents?

Hello Hifigeek1,
Could you please tell us the value of this bypass cap ?
Some time ago the ARC importer give me the new 6550 tube , but said to me the 4 bypass caps would not give me a better sound .In my schematics the 4 caps are of course not mentioned . They are listed however in the CD7 and installed in the factory.In this schematics ( SEP 26 05 )
C5,6 are listed as 0,0024mF 500V INFINICAP.Did not verify in my CD7

As I explained above .0024 mfd caps will not give you better sound and are not coupling caps. You can try emailing the factory for this information.
